Auto body and frame puller

ABSTRACT

An auto body and frame puller which includes a generally horizontal box girder base member supported on casters for moving from place to place. An upright post is supported from the base member and has a plurality of vertically spaced eyes for attachment of one block of a block and fall. A winch on the base member is provided for winding in the block and fall cable under power. A hook is provided on a second block of the block and fall for attachment to a portion of the frame to be straightened and a second hook on the outer end of the base member has a chain attached thereto for connection to the opposite side of the frame to be straightened. Operation of the winch causes the second block to move toward the post to pull on the portion of the frame to be straightened. The first block can be hooked into anyone of the eyes on the post to vary the direction of the pull with respect to the horizontal.

An upright post is supported from the basemember and has a plurality of vertically spaced eyes for attachment ofone block of a block and fall. A winch on the base member is providedfor winding in the block and fall cable under power. A hook is providedon a second block of the block and fall for attachment to a portion ofthe frame to be straightened and a second book on the outer end of thebase member has a chain attached thereto for connection to the oppositeside of the frame to be straightened. Operation of the winch causes thesecond block to move toward the post to pull on the portion of the frameto be straightened. The first block can be hooked into anyone of theeyes on the post to vary the direction of the pull with re spect to thehorizontal.

5 Claims, 7 Drawing Figures 1 AUTOBODY AND FRAME FULLER BACKGROUND OFTHE INVENTION 1. Field of the Invention The present invention isdirected to an auto body and frame puller.

2. Summary of the Invention The auto body and frame puller includes anelongate base member supported on casters and carrying an up right postthereon. The post has a plurality of vertically spaced block and fallattaching eyes and a winch onthe base member is provided for winding inthe cable of the block and fall. An opposition chain is connected to thefar end of the base member for connection to the opposite side of theobject to which the block and fall is attached so as tospread the devicebeing straightened as the winchis operated.

The primary object of the invention is toprovide a complete selfcontained auto body and framepuller actuated byan electric winch.

Other objects and advantages will become apparent in thefollowingspecification when considered in the light of theattacheddrawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of theinvention; FIG-2 is a top plan view of the invention;

FIG. 3 is-a bottom planview of the invention;

FIG. "4 is a vertical longitudinal sectional view,taken DESCRIPTION OFTHE PREFERRED EMBODIMENT Referring now to the drawings in detail,wherein like reference characters indicatelike parts throughout theseveral figures, the reference numeral indicates generally an automobilebody and frame puller constructed in accordance with the invention.

The automobile body andframe puller 10 includes an elongate boxgirderbasemember 11 arranged in generally horizontal relation supportedon a transverse horizontal plate 12 having a peripheral upstandingflange 13 rigidly secured thereto. The plate 12 and flange 13 form traysfor tools and parts. Casters 14 are secured to the tray 12 on oppositesides thereof for supporting the plate 12 and thereby the base 11.

A rectangular socket 15 is slidably engaged over the base member 11 andis secured in adjusted position therealongby set screws 16. A bar 17extends horizontally across the bottom of therectangular socket member15 and supports a pair of casters l8 therebeneath at opposite endsthereof. The socket l5 and casters 18 support the outer end of the basemember 11. A generallyrectangular socket member 19 is rigidly secured tothe outer ends of the base member 11 and has a chain hook 20 rigidlysecured to the upper portion thereof.

along the line 4'4 of FIG. 2, looking in the direction A socket member21 encompasses the base member 11 at the end thereof opposite the socketmember 19 and is rigidly secured thereto by welding of the like. An eyebeam 22 has its lower end rigidly secured to the socket member2l andslopes upwardly and forwardly therefrom. A generally rectangular socketmember 23 is rigidly secured to the upper end of the eye beam 22 and hasan upright post 24 rigidly secured therein ina position overlying andaligned with the base member 11. A pair of angular braces 25 are rigidlysecured to opposite sides of the eye beam 22 adjacent the lower endthereof and to the lower end of the post 24 on opposite sides thereof. Asecond pair of angular braces 26 are rigidly secured to opposite sidesof the base member 11 and to opposite sides of the lower portion of thepost 24.

the eyes 27. Anelectric winch 32 ismounted on the basemember 11 underthe post24 and has a cable 33 wound thereon and extending outwardlytherefrom. The cable 33 has its farend connected to a hook 34 which isengaged with a second selected one of the eyes :27. The cable33 istrained overadoublepulley block 35 carryinga hook 36 and is trained overthe singlepulley block 30 prior to extending to the hook 34. Operationof the winch draws the cable 33 inwardly so as to move the block 35toward the block30 to draw the hook36toward the post24.

In the use and operation of the invention base member 11 is rolled undera vehicle to have its frame straightened or some portion of its bodystraightened and the hook -29 isengaged with one side of the object tobe straightened and the hook36 isengaged with the opposed side ofthesame object. The electric winch 32 is then actuated to cause the objectto be pulled until straight whereupon the pressure is released. Bymoving the block 30 to other of the eyes-27 the direction of pull withrespect to the vehicle can be adjusted.

The socket member 15 can be adjusted longitudinally of the base member11 so as to give the desired support when needed. I

Having thus described the preferredembodiment of the invention it shouldbe understood that numerous structural modifications and adaptations maybe resorted to without departing from the spirit of the invention.
